Specific Question

Do darker colors affect your eyesight more than lighter colors?

Hypothesis

It is hypothesized that when you stare at colors for long periods of time it effects your vision.

Graph of Hypothesis

Variables

Independent Variable: colors

Dependent Variable: distance words are read

Variables That Need To Be Controlled:

1. How long the subjects stare at the color

2. The time the subject gets to the line

3. If they stay at the line too long

4. covering the other words

5. People follow the same order as the others did

6. Everyone stares at the same words

7. Everyone stares at the same colors

8. Everyone has to start at the 10 meter line and move up

9. Everyone has to stare at the colors as close to the screen as the others did

10.

Vocabulary List That Needs Explanation

Waves- Waves have high and low points, and the distance between one of those highs and lows and the next is called a wavelength. Just how long that wave is will determine the amount of energy that it has.

General Plan

The experiment will either take place in Mr.Yahna's room or in the library whichever is available at the time.

I will take them to either these two places during science class, I will gather the subjects during class time then

take them to the setup then put them through the trials. If the subjects do not get to the line fast enough I will ask them to go back and stare for an extra 10 seconds so they still see afterimages. If they do not

Potential Problems And Solutions

Safety Or Environmental Concerns

One safety concern is that the colors may hurt the subjects eyes after staring at the various different colors.

Experimental Design

(add the correct headings from the experimental design page before beginning)

Resources and Budget Table

Item	Number needed	Where I will get this	Cost
paper	1	chula printer
measuring tape	1	Yahna's room
computer	1	library or Yahna's room

Detailed Procedure

MATERIALS:

• measuring tape that stretches to 10 meters long

• printed out words that have a certain color font opposite to the color the subject stared at

• a black card with a rectangle cut out of it

• notebook

• pencil

• subjects willing to follow through with the experiment

• computer

• stopwatch

SETUP:

1. The subject(s) will meet in the library where the experiment will take place

2. The measuring tape will be stretched from the entrance doors to the exit doors (10m)

3. There will be 6 computers all with a different color on the screen set up

4. The stopwatch will be set to 1 minute ready to countdown

5. The black card will cover every other word but the on in the cutout portion of the card so the subject cannot read the other words for their next trial

PROCEDURE:

1. The subject will stare at the screen of the first color I choose for 1 minute when I start the stopwatch

2. The subject will stare from 4 inches away until the timer goes off

3. After that the subject will stand at the 10m mark which is the entrance door

4. The subject will try to read the word not covered by the black card

5. If the subject does not read the word from the starting point they will move forward 1m

6. For every time they do not read correctly they will move up 1m until they reach the point where the word is readable to them

7. When the subject reads the word they will stay put where they are then the meter number where they are standing will be recorded.

8. The subject then will stare at the color next on the list for 1 minute and repeat the process until we are finished with our last color to record

9. At the end of the experiment the data written down will be copied into the google doc SFP chart.

Results
The average distance the subject had to move up for red was 7.11m. The average distance for blue was 7.02m. For Green the average was 8.06m for purple the average is 7.45 and yellow is 6.63. The last color, orange, had an average of 6.14. The color the subjects had the least trouble with was orange, the color they had the most trouble with was green.


Conclusion
The experiment was run to see if staring at colors can dramatically affect your eyesight. It was shown that the people that stared at lighter colors had the least trouble with reading the words. The darker colors the subjects stared at made them have to move further than the lighter colors did. Yellow and orange were the top 2 colors that gave the least effect as for green and purple they both gave a greater effect.

Discussion

Discussion Essay:Alex Woodie 3-26-13 C block Does staring at colors for long periods of time affect your eyesight? The results of the experiment answered the question quite clearly by saying that the lighter the color you stare at the easier it is to read the darker words, and when you stare at darker colors it is harder to read lighter words. This is simple to explain because you need lots of light to read words, you would not write with a black crayon on a black piece of paper, because you cannot see it, you would put it on a white sheet of paper so you can see it clearly. It is hypothesized that all of the lighter words one has to read will be harder to read than darker words. The hypothesis is supported 100% by the experiment trials, the top two lightest colors which were Yellow and Orange had proof that this hypothesis is true. The color Orange had an average distance of 6.14meters, and Yellow had an average distance of 6.63meters. Then, we have the top two darkest colors the subjects had to stare at which were Green and Purple. Green had an average distance of 8.06meters, and Purple had an average distance of 7.45meters. As you can see the subjects had to move more forward by starting at darker colors. These results happened because of afterimages, the colors we see after we look at another for a decent amount of time. “When we stare at a bright object for some time, there is a fatigue of the retinal process. Because of this fatigue, when the image disappears, we see the complementary color.”This causes the afterimage to linger into any object we try to observe after we have fatigue. For worry about them in the future.example when you look at the color Red for a while, then look at a white object you will see Blue which is in this case the complementary color. Some problems that arose during my process is that the measuring tape would fold over, get tangled, move out of place, and pulled by accident this throws off my data making the data not true if I measure this way. I could have done this experiment more thoroughly, and accurate because I moved faster in this experiment than was needed to, get experiments done in the beginning so you do not have to worry about them in the future. There was no new technology used during the experiment. It can really make an impact on people who want to know if they have distorted vision or if it is simply afterimages. This can be very helpful to doctors, such as eye surgeons to know that certain parts of the eye react differently to different colors because if the patient wakes up and looks at something Yellow and sees it Purple without looking at previous colors there is something wrong with the patients eyes. Another question that would be of use to experiment on can be are there any ways to make your eyes see objects that look small big, and objects that are big smaller? Do you see better when your eyes are dry or when they are moist? Does pupil color affect your vision? How far can peripheral vision expand? These are good questions to follow up from my previous experiment.

Background Research

1. Scientists have found out that bright colors tire the eyes because they reflect the most light this is why most people cannot stare at bright colors for long. The color that makes the eye work too much is the color yellow.

2. before the topics of light can be explored, there must first be an understanding of waves. Waves have high and low points, and the distance between one of those highs and lows and the next is called a wavelength. Just how long that wave is will determine the amount of energy that it has. For example, a long wave has a low amount of energy or low frequency, and a short wave has a high amount of energy or high frequency.

3. One of the most dramatic experiments to perform is the demonstration of the blind spot. The blind spot is the area on the retina without receptors that respond to light. Therefore an image that falls on this region will NOT be seen. It is in this region that the optic nerve exits the eye on its way to the brain.

4. The human eye can see 7,000,000 colors. Some of these are eyesores. Certain colors and color relationships can be eye irritants, cause headaches, and wreak havoc with human vision. Other colors and color combinations are soothing. Consequently, the appropriate use of color can maximize productivity, minimize visual fatigue, and relax the whole body.

5. When the screen goes white, most people will see an after image of the US flag. When we stare at a bright object for some time, there is afatigue of the retinal process. Because of this fatigue, when the image disappears, we see the complementary color. The complementary color may linger for some time until the retinal process dies out.

6. Yogi Berra said "You can observe a lot by just watching.". Afterimages are the images you see after staring at an object for several seconds and then looking away. You will also learn how different cone cells in your retina respond to different colors.

7.redis all about energy and vitality, but it can also indicate anger. And of course it's associated with sexuality as well.

orange is stimulating, good for times when we just can't seem to get started with something. Its lighter version, peach, may be useful for exhaustion due to stress.

yellow is good for mental activities like reasoning and analysis. It can promote self-confidence and is helpful in situations when you need to be more optimistic.

green. It's about connections - with nature, or with our fellow humans. It's also good for general stress, since it can help balance emotions.

blue is soothing and relaxing. It can stimulate creativity. Light blue can denote quiet, and dark blue can be sedating. But too much dark blue can be depressing.

purple is related to imagination, intuition, and insight. In some situations it can also be very peaceful.
